What are the wavelengths of radiowaves?

Electromagnetic waves, such as radio waves and light waves, travel in a vacuum at 300,000,000 meters per second so the wavelength of a radio wave at any particular frequency can be calculated by using the formula:

[Wavelength in meters (m)] =

300,000,000 / [Radio frequency in cycles per second (Hz)]

AM (Medium and long wave) broadcasts:
Frequencies: 300 to 3,000 kilohertz (KHz)
Wavelengths in air: 1,000 meters to 100 meters

FM (UHF radio and television broadcasts):
Frequencies: 300 to 3,000 megahertz (MHz)
Wavelengths in air: 100 centimeters to 10 centimeters

What is one rock radio station?

How do you remove a radio from a 2006 Chevy Malibu?

1. Pull both side console panels off the center console. (These are by your feet in the front).

2. Remove the screw on either side that has the shifter panel attached.

3. Pull the shifter panel up at the rear and down at the front to pop it off and pull it back a little. It won't remove completely due to the shifter.

4. Remove the two screws that you just exposed below the traction control/hazard/airbag panel and disconnect the wires attached to the panel.

5. Carefully pull the trim up from around the HVAC controls and the radio. You also have to remove the center wood piece.

6. Now you can remove the screws holding the HVAC and the radio in place and pull the radio out.

clarification of what is meant by "bleed". That's a term with which our crack team of

What is longwave radio?

Transmitters before 1924 were long wave transmitters this is the lowest band in the RF spectrum 148.5 to 283.5 kHz. Propagation of shorter wavelengths was not understood until the shortwave experiments by amateur radio operators in 1923 and by Marconi in 1924. Spark-gap transmitters were used prior to World War I, until the development of powerful Radio alternators by General Electric just prior to the war. Vacuum tubes began to be used to generate radio frequencies in the mid-1920s.

After 1924, use of long wave radio for long distance communication began to decline, as much less expensive shortwave transmitters began to carry increasingly heavy volumes of long distance communication. A period of explosive growth of shortwave communications began in 1927, leading to rapid decline in long wave radio usage.

Explain why the energy of infrared waves is greater than the energy of radio waves?

The energy of infrared waves is greater than the energy of radio waves. This is because infrared waves has a smaller wavelength compared to radio waves. The smaller the wavelength, the higher the energy.

What code unlocks the radio for a 2000 Oldsmobile silhouette?

Enter your secret code as follows; pause no more than 15 seconds between steps:

1. Turn the ignition on. LOC will appear on the display.

2. Press MN and 000 will appear on the display.

3. Press MN again to make the last two digits agree with your secret code.

4. Press HR to make the first two digits agree with your secret code.

5. Press AM-FM after you have confirmed that the code matches the secret code you have previously written down. The display will show SEC, indicating is now operable and secure.

If you enter the wrong code eight times, INOP will appear on the display. If this happens you have to leave the ignition on for at least an hour and at that point it will give you three more tries.

If the code is lost or forgotten you have to contact the dealer to have them reset it for you.

What are radio stations in the 1920?

Station KDKA in Pittsburgh is considered to have become the first broadcasting

station in the USA, in November of 1920.

Before that, 'radio' was uncheduled, irregular, and unregulated transmissions

by people who liked to tinker and build things in their garage, talking through

their home-brew transmitters occasionally, for the enjoyment of others in the

neighborhood who liked to build home-brew receivers in their garage. A lot like

'ham' operators, except that they didn't expect to hear any response coming back.

Yes, and so did every other Apollo mission. The moon blocks the communication signals from being sent to Earth, and contact was only regained when the spacecraft began to emerge around the other side.

Do radio waves get through earth's atmosphere?

No, radio signals can come from broadcasting towers and can be received by radios, without the need for satellites; indeed, radio broadcasting originated long before the first satellite was launched.

How do you remove the radio on a 1993 Saturn stationwagon?

The fascia that covers the center air vents down to the space just above the ashtray and console must be removed, this is fairly easy to do, just take hold of it and pull straight back toward you. It will make a sound like you are breaking it but it will pop off. The rest is fairly obvious, you will see Hex head screws remove them around the radio and then extract the radio from its space, on the back of the unit, press the connector tabs in and remove the connector and next the antenna wire.
